Description

Technical Field

[0001] The invention relates to the technical field of sowing, in particular to an anti-clogging corn sowing device. Background Art

[0002] A corn seeder is a planting machine that sows corn seeds, and can also take into account crops such as soybeans. The working principle of a corn seeder is mainly to drive the seed meter and fertilizer meter to work through the rotation of the ground wheel. The seed meter discharges the corn seeds evenly according to the set sowing amount and plant spacing. The seeds fall into the opened sowing furrow through the seed delivery tube. At the same time, the fertilizer meter applies fertilizer near the seeds according to the requirements of the fertilizer application amount. When sowing, a large amount of corn seeds will be placed in the seed storage box, which can avoid frequent seed addition. A large amount of corn seeds will accumulate in the feed tube. Since the surface of the corn seeds will be coated with pesticides, This causes the corn seeds to stick together. If too many corn seeds are piled up in the feed pipe, the mutual squeezing between the seeds will cause the seeds to stick together. When the seeds stick together, the seed meter cannot discharge the seeds evenly according to the set sowing amount and plant spacing during operation, because the stuck seeds may be discharged in clumps instead of single grains or several evenly distributed grains together. This will cause uneven distribution of seeds in the field. If the stuck seed clumps are large, they may get stuck when passing through the narrow part of the feed pipe or the seed discharge port, thereby hindering the normal discharge of subsequent seeds and causing the seeder to be blocked.

Detailed implementation manners

[0033] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given in conjunction with the accompanying drawings of the specification.

[0034] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0035] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present invention. The "in one embodiment" appearing in different places in this specification does not all refer to the same embodiment, nor is it a separate or alternative embodiment that excludes other embodiments.

[0036] Embodiment 1

[0037] Referring to Figures 1-7 , for the first embodiment of the present invention, this embodiment provides an anti-blocking corn seeding device. The anti-blocking corn seeding device includes a seeding assembly 100, including a frame 101. A seed metering device 102 is arranged on the frame 101. A blanking pipe 103 is fixed on one side of the seed metering device 102. A seed storage box 104 is fixed on the top of the blanking pipe 103.

[0038] On the frame 101, there are components such as ground wheels for the auxiliary seed metering device 102. The seed storage box 104 is used for storing and discharging corn seeds. The feeding pipe 103 is connected to the seed metering device 102 and is used to convey the seeds inside the seed storage box 104 to the seed metering device 102. In this way, the sowing of corn seeds can be completed through the seed metering device 102. This is the prior art, and this solution will not be elaborated much here. And those skilled in the art can clearly understand the working principle.

[0039] The anti-blocking component 200 is arranged inside the feeding pipe 103 and includes a feeding part 201. The feeding part 201 includes a rotating cylinder 201a. The rotating cylinder 201a is rotationally connected to the feeding pipe 103 through a rotating shaft. A baffle block 201b is fixed inside the feeding pipe 103. One side of the baffle block 201b is attached to the rotating cylinder 201a and is movably connected to the rotating cylinder 201a. The rotating cylinder 201a is provided with a feeding groove 201a-1. A motor 201c is fixed on one side of the feeding pipe 103. The output shaft of the motor 201c is fixed to the rotating cylinder 201a.

[0040] There are two baffle blocks 201b, which are respectively located on both sides of the rotating cylinder 201a. The tops of the two baffle blocks 201b are both inclined. The two baffle blocks 201b are used to block both sides of the rotating cylinder 201a to prevent the seeds inside the seed storage box 104 from falling downward through both sides.

[0041] The motor 201c is fixed to one side of the feeding pipe 103 through a bracket and is used to drive the rotating cylinder 201a to rotate. When the feeding groove 201a-1 of the rotating cylinder 201a rotates to the upper side, the seeds inside the seed storage box 104 will enter the inside of the rotating cylinder 201a through the feeding groove 201a-1. When the feeding groove 201a-1 rotates to the lower side, the seeds inside the rotating cylinder 201a will fall downward. In this way, the seeds inside the seed storage box 104 can be conveyed into the feeding pipe 103, and the seeds will be conveyed quantitatively, so as to avoid excessive accumulation of seeds inside the feeding pipe 103, which may cause the seeds to stick to each other, resulting in blockage inside the feeding pipe 103. And the feeding speed of the rotating cylinder 201a for the seeds is slightly faster than the sowing speed of the seed metering device 102, so that the seeds inside the feeding pipe 103 can always be kept sufficient.

[0042] The anti-blocking component 200 further includes a dredging part 202. The dredging part 202 includes a movable frame 202a. The movable frame 202a is located inside the feeding pipe 103. A reciprocating roller 202b is rotationally connected inside the feeding pipe 103. A fixed sleeve 202c is fixed to the inner side of the feeding pipe 103. A fixed shaft 202d is fixed inside the fixed sleeve 202c. The fixed shaft 202d is engaged with the reciprocating roller 202b.

[0043] The movable frame 202a is rectangular, and four pusher rods are fixed inside. When the reciprocating roller 202b rotates, it will drive the fixed sleeve 202c and the movable frame 202a to move up and down through the fixed shaft 202d. When the movable frame 202a moves up and down, it can dredge the inside of the blanking pipe 103 and disperse the adhered corn seeds, so as to avoid the situation that the seed metering device 102 will have missed sowing due to the blockage inside the blanking pipe 103.

[0044] Embodiment 2

[0045] Refer to Figures 2-12 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0046] Specifically, the anti-blocking component 200 further includes a transmission member 203. The transmission member 203 includes a worm gear 203a. The worm gear 203a is fixed to the top end of the reciprocating roller 202b. A protective box 203b is arranged outside the worm gear 203a. A worm 203c is rotatably connected inside the protective box 203b. The worm 203c meshes with the worm gear 203a. One end of the worm 203c penetrates to the outside of the blanking pipe 103 and is rotatably connected with a first belt pulley 203d through a bearing. A second belt pulley 203e is fixed to the outside of the output shaft of the motor 201c. The first belt pulley 203d and the second belt pulley 203e are connected by a belt drive.

[0047] The protective box 203b is fixed to the inner wall of the blanking pipe 103 through a mounting column. The top of the protective box 203b is conical, which can avoid the situation that corn seeds will accumulate on the top of the protective box 203b. The protective box 203b is used to protect the meshing part of the worm 203c and the worm gear 203a to avoid the situation of seed jamming between the two.

[0048] When the motor 201c rotates, it will drive the second belt pulley 203e to rotate. The second belt pulley 203e drives the first belt pulley 203d to rotate through the belt. When the first belt pulley 203d is connected to the worm 203c, the first belt pulley 203d will drive the worm 203c to rotate and make the worm 203c drive the worm gear 203a to rotate, so that the worm gear 203a can drive the reciprocating roller 202b to rotate.

[0049] Specifically, the anti-blocking component 200 further includes a connecting member 204. The connecting member 204 includes a gear 204a. The gear 204a is located outside the worm 203c. A clamping groove 203c-1 is formed on the worm 203c. A clamping block 204b is fixed to the inner side of the gear 204a. The clamping block 204b is clamped with the clamping groove 203c-1. A tooth groove 203d-1 is formed on the inner side of the first belt pulley 203d. The gear 204a is matched with the tooth groove 203d-1.

[0050] Through the cooperation of the card slot 203c-1 and the card block 204b, it is used to connect the gear 204a and the worm 203c, so that the gear 204a can move horizontally outside the worm 203c and can drive the worm 203c to rotate.

[0051] When the gear 204a moves into the tooth groove 203d-1 and meshes with the tooth groove 203d-1, when the first pulley 203d rotates at this time, it can drive the gear 204a to rotate, so that the gear 204a can drive the worm 203c to rotate.

[0052] Specifically, a force-bearing block 204c is fixed on one side of the gear 204a, an extrusion rod 204d is arranged on one side of the blanking pipe 103, a first spring 204e is fixed on one side of the force-bearing block 204c, the other end of the first spring 204e contacts the first pulley 203d, and the force-bearing block 204c is conical.

[0053] When the extrusion rod 204d rotates, it will approach the force-bearing block 204c. When the extrusion rod 204d rotates a certain angle and squeezes the inclined surface of the force-bearing block 204c, it can push the force-bearing block 204c to move, so that the force-bearing block 204c can drive the gear 204a to mesh with the tooth groove 203d-1.

[0054] When the extrusion rod 204d is separated from the force-bearing block 204c, a thrust can be applied to the force-bearing block 204c through the first spring 204e, so that the force-bearing block 204c drives the gear 204a to separate from the tooth groove 203d-1.

[0055] Specifically, the anti-blocking assembly 200 further includes a trigger member 205. The trigger member 205 includes a rotating plate 205a. A support shaft 205b is fixed on one side of the rotating plate 205a. One end of the support shaft 205b penetrates to the outside of the blanking pipe 103 and is rotatably connected to the inside of the blanking pipe 103. The extrusion rod 204d is fixed to the outside of the support shaft 205b. A rotating frame 205e is sleeved on the outside of the rotating plate 205a. One end of the rotating plate 205a is rotatably connected to a connecting rod 205c through a rotating shaft.

[0056] The number of the rotating plate 205a and the rotating frame 205e is two, which are arranged up and down. The connection state of the two rotating frames 205e is V-shaped. The two rotating frames 205e are connected through the connecting rod 205c, so that the two rotating frames 205e can rotate simultaneously.

[0057] If there is no accumulation of seeds inside the blanking pipe 103, the height of the seeds will not contact the rotating frame 205e. At this time, the rotating frame 205e will remain in the current state.

[0058] When the seeds inside the blanking pipe 103 accumulate due to adhesion, and at this time seeds continue to fall downward from above, the seeds inside the blanking pipe 103 will continue to increase in height. When its height contacts the rotating frame 205e, it will exert a squeezing force on the rotating frame 205e and cause the rotating frame 205e to rotate towards one side of the inner wall of the blanking pipe 103. When the rotating frame 205e rotates, it will drive the rotating plate 205a and the support shaft 205b to rotate. In this way, the support shaft 205b can drive the extrusion rod 204d to rotate, and the extrusion rod 204d can squeeze the force-receiving block 204c.

[0059] By setting two groups of rotating plates 205a and rotating frames 205e, it can be ensured that whether the accumulation inside the blanking pipe 103 is from bottom to top or from top to bottom, the rotating frame 205e and the rotating plate 205a can rotate.

[0060] Specifically, a guide plate 205d is fixed on one side of the inner wall of the blanking pipe 103, and the guide plate 205d is inclined downward.

[0061] Through the setting of the guide plate 205d, it is used to concentrate the falling corn seeds on one side of the rotating frame 205e, and when the seeds below increase upward, they will also be concentrated on one side of the rotating frame 205e.

[0062] Embodiment 3

[0063] Refer to Figures 1-13 , which is the third embodiment of the present invention, and this embodiment is based on the first two embodiments.

[0064] Specifically, the anti-blocking component 200 further includes an intercepting member 206. The intercepting member 206 includes a baffle plate 206a. A slot 201b-1 is formed in the material blocking block 201b, and the baffle plate 206a is inserted into the slot 201b-1. A fixing rod 206b is fixed at the bottom of the baffle plate 206a. A support frame 206c is fixed on the inner wall of the blanking pipe 103. A moving plate 206d is inserted into the support frame 206c. A positioning shaft 206e is fixed at the end of the moving plate 206d. A positioning groove 206b-1 is formed on the fixing rod 206b, and the positioning shaft 206e slides in the positioning groove 206b-1.

[0065] The baffle plate 206a is arc-shaped. The support frame 206c is used to support the moving plate 206d. When the moving plate 206d moves, it will drive the fixing rod 206b to move through the cooperation of the positioning groove 206b-1 and the positioning shaft 206e. In this way, the fixing rod 206b can drive the baffle plate 206a to move towards the bottom of the rotating cylinder 201a, so as to intercept the seeds falling inside the rotating cylinder 201a, thereby avoiding blockage inside the blanking pipe 103. When seeds continue to fall from above while the blockage situation inside the blanking pipe 103 will be aggravated.

[0066] Specifically, a connecting column 206f is fixed to one side of the moving plate 206d. A moving groove 103-1 is formed in the blanking pipe 103. The connecting column 206f slides in the moving groove 103-1. A rotating rod 206g is fixed to the outside of the support shaft 205b. An extrusion groove 206g-1 is formed in the rotating rod 206g. The support shaft 205b is movably connected to the inside of the extrusion groove 206g-1.

[0067] When the upper support shaft 205b rotates, it drives the rotating rod 206g to rotate. The rotating rod 206g drives the connecting column 206f to move through the cooperation of the extrusion groove 206g-1, so that the connecting column 206f can drive the moving plate 206d to move.

[0068] Specifically, a positioning column 206h is fixed to one side of the rotating rod 206g. A positioning block 206i is fixed to one side of the blanking pipe 103. The positioning column 206h is movably connected to the inside of the positioning block 206i.

[0069] The positioning column 206h is arc-shaped and is coaxial with the rotation angle of the rotating rod 206g. Through the cooperation of the positioning column 206h and the positioning block 206i, it is used to position the rotating rod 206g.

[0070] Specifically, a second spring 206j is sleeved on the outside of the positioning column 206h. The two ends of the second spring 206j are respectively fixed to the positioning block 206i and the rotating rod 206g.

[0071] When the seeds are cleared and the height drops, at this time, a thrust is applied to the rotating rod 206g through the second spring 206j to reset the rotating rod 206g, and at the same time, the baffle 206a and the rotating plate 205a are reset.

[0072] During use, when sowing, the motor 201c is started to drive the rotating cylinder 201a to rotate. When the feed slot 201a-1 of the rotating cylinder 201a rotates to the upper side, the seeds in the seed storage box 104 will enter the inside of the rotating cylinder 201a through the feed slot 201a-1. When the feed slot 201a-1 rotates to the lower side, the seeds inside the rotating cylinder 201a will fall downward. In this way, the seeds in the seed storage box 104 can be conveyed into the blanking pipe 103, and the seeds will be conveyed quantitatively, so as to avoid too many seeds accumulating inside the blanking pipe 103, which will cause the seeds to stick to each other and block the inside of the blanking pipe 103. And the seed discharging speed of the rotating cylinder 201a is slightly faster than the sowing speed of the seed metering device 102, so that the seeds inside the blanking pipe 103 can always be kept sufficient.

[0073] When the seeds inside the blanking pipe 103 accumulate due to adhesion, and at this time seeds continue to fall downward from above, the seeds inside the blanking pipe 103 will continue to increase in height. When its height contacts the rotating frame 205e, it will exert a squeezing force on the rotating frame 205e and cause the rotating frame 205e to rotate towards one side of the inner wall of the blanking pipe 103. When the rotating frame 205e rotates, it will drive the rotating plate 205a and the support shaft 205b to rotate. In this way, the support shaft 205b can drive the extrusion rod 204d to rotate. When the extrusion rod 204d rotates, it will approach the force-receiving block 204c. When the extrusion rod 204d rotates a certain angle and squeezes the inclined surface of the force-receiving block 204c, it can push the force-receiving block 204c to move. In this way, the force-receiving block 204c can drive the gear 204a to engage with the tooth groove 203d-1.

[0074] At this time, when the first pulley 203d rotates, it can drive the gear 204a to rotate. In this way, the gear 204a can drive the worm 203c to rotate, and the worm 203c can drive the worm gear 203a to rotate. In this way, the worm gear 203a can drive the reciprocating roller 202b to rotate. When the reciprocating roller 202b rotates, it will drive the fixed sleeve 202c and the movable frame 202a to move up and down through the fixed shaft 202d. When the movable frame 202a moves up and down, it can dredge the inside of the blanking pipe 103 and disperse the adhered corn seeds, so as to avoid the situation that the seed metering device 102 will have missed seeding due to the blockage inside the blanking pipe 103.

[0075] When the upper support shaft 205b rotates, it will drive the rotating rod 206g to rotate. The rotating rod 206g drives the connecting column 206f to move through the cooperation of the extrusion groove 206g-1. In this way, the connecting column 206f can drive the moving plate 206d to move. When the moving plate 206d moves, it will drive the fixed rod 206b to move through the cooperation of the positioning groove 206b-1 and the positioning shaft 206e. In this way, the fixed rod 206b can drive the baffle 206a to move towards the bottom of the rotating cylinder 201a, so as to intercept the seeds falling inside the rotating cylinder 201a, and thus avoid the blockage inside the blanking pipe 103. When seeds continue to fall from above while the blockage situation inside the blanking pipe 103 will be aggravated.
